A magnitude-4.1 earthquake centered in the Hawthorne area was recorded this afternoon, but there were no immediate reports of damage.
The 3:49 p.m. temblor's epicenter was two miles northeast of Hawthorne, four miles east of El Segundo and 10 miles from the Los Angeles Civic Center.
Its depth was 7 1/2 miles, according to U.S. Geological Survey data.
The shaker followed a magnitude-4.7 temblor that struck shortly before 8:40 p.m. Sunday, a mile east of Lennox, a mile south southeast of Inglewood and 10 miles south southwest of the Los Angeles Civic Center.
As it did over the weekend, the Los Angeles Fire Department went into "earthquake emergency mode," which requires the nearly 1,100 on-duty LAFD personnel to actively survey the department's 471-square-mile jurisdiction from the ground and air, said spokesman Brian Humphrey.
Some minor damage was reported from Sunday's quake, such as broken windows at a business in Long Beach and items falling off store shelves, according to police and fire officials.
The rumbling on Sunday -- which was felt throughout the Greater Los Angeles area and as far away as San Diego and Riverside counties -- marked the strongest quake to strike the Southland since a magnitude-5.5 that hit Chino Hills last July 29.
